Why does the walls of the capillaries and the alveoli have to be thin?

If their walls are too thick, substances like oxygen and nutrients and waste cannot pass across the cells into or out of the body.

Oxygen passes into the capillaries that surround these sac?
Oxygen passes into the capillaries that surround the alveoli. The thin walls of the capillaries make this diffusion easier.
Where does gas exchange occur?
gas exchange occurs between the thin walls of the alveoli and the thin walls of the capillaries
Why do the walls of the capillaries and aveoli need to be thin?
The walls of alveoli are thin to allow the exchange of gases (Co2 and O2) between blood capillaries and the aveoli in the lungs.
Why do lungs have thin permeable walls?
diffusion of gases (oxygen and carbon dioxide) to & from air in lungs and capillaries in alveoli
What are alveoli surrounded by?
the blood surround Alveoli in order to gas exchange between the Alveoli and red blood cell.
How does the respiratory connect to the circulatory?
There is no anatomical connection of circulatory system with the respiratory system. Blood capillaries come in close contact with the lung alveoli. The area of contact is about 1000 square feet. But there are two thin membranes to separate blood and air. The walls of capillaries and the walls of alveoli. Both have flat and thin epithelium. The gases readily pass across these membranes.
What tissue is the walls of the alveoli composed of?
the walls of the alveoli are very thin but strong layers of elastic tissue lines with a single layer of flattened epithelium.
What is the body organ which oxygen passes through to capillaries?
The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.

Why do capillaries have such thin walls?
Capillaries have thin walls to optimise the level of diffusion of oxygen and other nutrients in the blood stream to the surrounding cells.
Why are capillaries and not arteries or veins found in alveoli nephrons and villi?
vessel walls must be thin to allow ease to transfer of molecules to these tissues i had this on a test and i got it right :)
How is Alveoli well adapted to diffusion?
The alveoli have very thin walls, which allow for rapid diffusion into the surrounding capillaries. There are also many alevoli in the lung, and that increases the surface area dramatically, allowing for more diffusion to occur
